Converting Vampires into my own Vampires

[Day 200]

Last night, after eating the leftover flesh of the muscle beast, I obtained a Vampire Lineage, the Lineage from the Vampire Family from Thanatos, but it was "suppressed" and "assimilated" by my own Bloodline, as the System stated that mine was superior… Did my Bloodline obtain some kind of Devour effect?

Well, that means that no god will try to brainwash me at very least, and the Goddess of Blood who owns this Bloodline didn't speak to me in my dreams or anything, so I should be fine. I also doubt that Jormungandr can speak to me without my consent as well unless they use Dreams, but I can choose to wake up and instantly close the connection within Dreams at the very least.
